🎓 ApruebaYA — Flagship / Thesis ProjectWeb platform connecting Ecuadorian university students with qualified tutors, automatically generating AI-powered exam simulations from each session's material. Highlights: standalone FastAPI microservice acting as an orchestration layer for AI-generated simulations (DeepSeek, Grok), decoupling business logic from external model consumption · automatic geographic access restriction by IP · tutor review flow before publishing AI-generated content
|
Full-stack POS + e-commerce platform running on the same database, with end-to-end idempotency, an expiring discount engine, and an inventory-aware AI chatbot. Highlights: idempotency via unique UUID + database-level constraint · simulated checkout with card validation (Luhn algorithm) and masked card data · Strategy, Singleton and Builder patterns · Gemini AI chatbot with role-based prompts · automated test coverage (Pytest, Django TestCase)
|
Platform centralizing role-based surveys (student/teacher) on AI chatbot usage in education, with enriched statistics and Excel export. Highlights: Repository + Factory + Observer layered architecture · idempotency via HTTP header + unique index · automatic retry with exponential backoff on deadlocks
